In this scenario we will see a file created on the upstream server and attempted replication with its downstream partner. RPC traffic is being blocked between the machines by an incorrectly configured firewall. This is a common scenario and basic understanding of firewalls, TCP/IP, ports, and RPC is assumed. Debug logging severity is set to 5 in order to see more details about the problem state.

(rpcportsblocked – Dfsr00008 – 2008.log)

These are two Windows Server 2008 servers called 2008x86SRV10 and 2008x86SRV11 in the contoso.com domain. The log is from 2008x86SRV10 where the file is created (upstream). Both servers are participating in the RpcPortRG replication group for the RpcportRf replicated folder. The file is called “fveupdate.exe”.
